Dissolving Materials
Use chemicals to dissolve the materials underneath the gold of circuit boards. CBX and StripFree products work well but do have drawbacks. CBX is a powder that is good to use in areas where not a lot of other metal types are close. It will be used too quickly otherwise, reducing its cost effectiveness. StripFree should be used when an item is stainless steel based, as the solution uses an electric current to separate the gold from the board. It does require access to a car battery to work, however.
Acid Baths
Use an acid bath. While the chemicals above dissolve the materials beneath gold, acid baths are designed to dissolve the gold itself. Aqua Regia is an acid used to submerge the circuit boards. Once the boards are removed from the acid, the remaining brown, murky water will contain dissolved particles of gold. This process uses highly corrosive substances that have been made safer by the inclusion of SubZero as a replacement for nitric acid in traditional Aqua Regia. Protective clothing and precautions should still be taken when using an acid bath process.
Precipitant
Use a precipitant. Added to water, the precipitant will form a solution that will separate the gold from the acid. The separated gold, once the acid has been discarded, will resemble brown mud. At this point, no further chemicals or solutions will be needed to retrieve the gold. Washing the mud in aqua ammonia and tap water will result in a powder. The powder will then need to be melted to return the gold to its pure state.

Gold plating is generally found on circuit boards and fingers inside of computers. There are many ways to recover gold plating but one of the quickest and relatively safest ways is to soak your gold plated item in CBX circuit board stripping powder solution.
1.Put on protective eye goggles and waterproof gloves.
2.Pour out the contents of one jar of CBX circuit board stripping powder into a ceramic bowl or container. You can purchase the powder from shorinternational.com.
3.Add 1 gallon of water to the container and mix with a wood spoon.
4.Add your gold-plated material to the bowl and allow to soak for 6 to 8 hours.
5.Remove the gold-plated material from the solution and set aside. Make sure you are wearing waterproof gloves when you do this.
6.Set a coffee filter into another ceramic bowl or container and pour the liquid into the coffee filter. Lift up the filter as the bowl starts to fill up with liquid. The gold can be found in the filter.

Tungsten alloy swaging rod consists of W-Ni-Fe, W-Ni-Cu or W-Ni-Cu-Fe. Tungsten alloy swaging rod is made of tungsten alloy rod. After being swaged, the ultimate stensile strength can reach 1200 MPa or even 1400MPa. Tungsten alloy swaging rod is widely used in military industries. AS.34 Kormoran used tungsten alloy swaging rod as its warhead.
The AS.34 Kormoran is a German-produced Anti-ship missile. The Kormoran (cormorant) uses an inertial guidance system for the midcourse phase, switching to active radar homing during the terminal attack phase. It carries a 165 kg (363 lb) delay-fused warhead, designed for 90mm of penetration prior to detonation. The maximum range is 23 km (~14 miles).
With tungsten alloy swaging rod, AS.34 Kormoran can penetrate armor of ship more easily and destroy it.

Massive ordnance penetrator used tungsten alloy swaging rod as its warhead.
Massive Ordnance Penetrator (MOP)is a U.S. Air Force, precision-guided, 30,000-pound (13,608 kg) "bunker buster" bomb. This is substantially larger than the deepest penetrating bunker busters previously available, the 5,000-pound (2,268 kg) GBU-28 and GBU-37.
With tungsten alloy swaging rod, massive ordnance penetrator can penetrate deeper and destroy underground bunker.

Anti-ballistic missile used tungsten alloy swaging rod as .
An anti-ballistic missile (ABM) is a missile designed to counter ballistic missiles. Ballistic missiles are used to deliver nuclear, chemical, biological or conventional warheads in a ballistic flight trajectory. The term "anti-ballistic missile" describes any antimissile system designed to counter ballistic missiles. However, the term is used more commonly for systems designed to counter intercontinental ballistic missiles (ICBMs).
With tungsten alloy swaging rod, anti-ballistic missile counter ballistic missile by utilizing kinetic energy.
